Re: possible tobi/fake madara identity
Yes, it's said that Izuna died, but did he really..? Wasn't it only a fake death? After all, we know only about Izuna through Tobi's word of mouth and we know, we can't trust a person wearing a mask, someone who'd throw away his identity and become no one, only to complete his plan - the Moon's eye which originated from whom? Madara.
Both of them have some sort of connection otherwise why would Tobi want so bad to ressurect Madara? By dying Madara put his life in his hands and Tobi seemed so angry when seeing Madara as an edo.
Something else, when he talked about Izuna, Tobi clenched his arm - episode 140. Was he really just putting up an act or was is sth more? Because to me it didn't seem like an act as some of his other actions. The hatred towards Senju for example, only an Uchiha could hold a grudge so strong against the people who ruined their dreams. It seemed too real to be fake but still it's arguable.
Lastly, Izuna is a nameless shinobi much like Shisui. Someone who throws away his life for the greater good. Tobi denies his past self, now being no one. Zetsu was right in episode 32 - Tobi is a good boy, well, used to be.
More and more i'm starting to support the Tobi=Izuna theory but anything is possible in the Narutoverse. Well, as long as it makes sense and keeps me pumpin', i'm okay with it.
